IGP2 has been having problems where sometimes it turns off and requires simply unplugging and plugging back in.

Ion gauge has been replaced.

At first the vacuum box appeared red on epics and when attempting to reset everything nothing would work and the backing pump would try and turn on then timeout.

Apparently this new ion gauge draws slightly more than the old one and this blew a fuse in the PLC.

Old fuse was 2A, so a new 3A fuse has been replaced - seems to be working fine now.
